如何将 Apache Tiles 集成到 Spring 引导 Web 应用程序中？

Question

我想在我的 spring 引导应用程序中添加 apache 磁贴。

就像我们在 application.properties 文件中配置前缀和后缀一样，我想知道我们如何配置 tiles.xml。

我在 POM.xml 文件中添加了 apache tiles 的 Maven 依赖项，但是当我从我的控制器返回 tile 定义的名称时，它给出了 404 错误。

这是我的 POM.xml 文件

    <!-- https://mvnrepository.com/artifact/org.apache.tiles/tiles-jsp -->
    <dependency>
        <groupId>org.apache.tiles</groupId>
        <artifactId>tiles-jsp</artifactId>
        <version>3.0.8</version>
    </dependency>

这是我的 tiles.xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE tiles-definitions PUBLIC  "-//Apache Software Foundation//DTD Tiles Configuration 
3.0//EN"  "http://tiles.apache.org/dtds/tiles-config_3_0.dtd">
<tiles-definitions>
<definition name="home-page"
    template="/WEB-INF/layout/layout.jsp">
    <put-attribute name="body" value="/WEB-INF/pages/landing-page.jsp" />
    <put-attribute name="script" value="" />
    <put-attribute name="stylesheet" value="" />
</definition>
</tiles-definitions>

这是我的控制器方法

@Controller
public class LandingPage {

    @RequestMapping("/")
    public String landingPage() {
        return "home-page";
    }
}

这是我的 TilesConfig.java 文件

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.view.UrlBasedViewResolver;
import org.springframework.web.servlet.view.tiles3.TilesConfigurer;
import org.springframework.web.servlet.view.tiles3.TilesView;

@Configuration
public class TilesConfig {
    @Bean
    public UrlBasedViewResolver viewResolver() {
        UrlBasedViewResolver tilesViewResolver = new 
        UrlBasedViewResolver();
        tilesViewResolver.setViewClass(TilesView.class);
    return tilesViewResolver;
}

@Bean
public TilesConfigurer tilesConfigurer() {
    TilesConfigurer tilesConfigurer = new TilesConfigurer();
    String[] tilesXml = { "WEB-INF/tiles.xml" };
    tilesConfigurer.setDefinitions(tilesXml);
    return tilesConfigurer;
   }
}

Answer 1

确保您拥有静态资源并且视图位于正确的路径中。您可以按如下方式配置图块视图解析器。

@Bean
public UrlBasedViewResolver viewResolver() {
    UrlBasedViewResolver tilesViewResolver = new UrlBasedViewResolver();
    tilesViewResolver.setViewClass(TilesView.class);
    return tilesViewResolver;
}

@Bean
public TilesConfigurer tilesConfigurer() {
    TilesConfigurer tilesConfigurer = new TilesConfigurer();
    String[] tilesXml = { "WEB-INF/tiles.xml" };
    tilesConfigurer.setDefinitions(tilesXml);
    return tilesConfigurer;
}

您需要做的第一件事是在您的 configuration.I 中使用 @EnableWebMvc 添加到以下配置中您可以尝试将以下配置添加到您的应用程序中吗

public class MvcWebApplicationInitializer 
      extends AbstractAnnotationConfigDispatcherServletInitializer {

  // Load database and spring security configuration
  @Override
  protected Class<?>[] getRootConfigClasses() {
    return new Class[] { WebAppInitializer.class};
  }

  // Load spring web configuration
  @Override
  protected Class<?>[] getServletConfigClasses() {
    return new Class[] { WebMvcConfig.class };
  }

  @Override
  protected String[] getServletMappings() {
    return new String[] { "/" };
  }

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "your component scan packages" })
public class WebMvcConfig implements WebMvcConfigurer {

    /**
     * Initialise Tiles on application startup and identify the location of the tiles configuration file, tiles.xml.
     * 
     * @return tiles configurer
     */
    @Bean
    public TilesConfigurer tilesConfigurer() {
        final TilesConfigurer configurer = new TilesConfigurer();
        configurer.setDefinitions(new String[] { "WEB-INF/tiles.xml" });
        configurer.setCheckRefresh(true);
        return configurer;
    }

    /**
     * Introduce a Tiles view resolver, this is a convenience implementation that extends URLBasedViewResolver.
     * 
     * @return tiles view resolver
     */
    @Bean
    public TilesViewResolver tilesViewResolver() {
        final TilesViewResolver resolver = new TilesViewResolver();
        resolver.setViewClass(TilesView.class);
        return resolver;
    }

    @Override
    public void configureDefaultServletHandling(
      DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }
}
